I only have 1 key and need several more and don't want to spend $150 each. If I take the small transponder chip from the 1 original and attach into the column I could have as many as I would like really cheap. I could also cut the physical part of the key on a "regular" blank without the buttons and it would be small enough to fit in my pocket/key chain.

PS-I am a locksmith so cutting the key is no problem
